COLLAPSIBLE 0R FOLDING HOOD PARTICULARLY FOR VEHICLES.

rsoasse.

To all whom it may concern:

Be it known that I, ALFRED Kr'in'rii, a subject of the Emperor of Austria, residing in Berlin-Wilmersdorf, Germany, have invented certain new and useful. Improvements in Collapsible or Folding I-Ioods Particularly for Vehicles, of which the follow ing is a specification.

This invention comprises a collapsible or folding hood, more particularly for vehicles, arranged so that the rear part of the hood is positively connected to the front part and so that the folded hood does not project, or projects only very little, beyond the rear edge of the vehicle, whereby the hood can be stowed in the carriage body. This is effected by the last hoop instead of being pivoted directly to the main strut, being connected to the front part of the hood by a pivoted parallelogram or kind of lazy tongs. The rear projection of the hood can be thus varied within very wide limits, the hood in a folded state always occupying the same space.

The figure is a longitudinal vertical sectional view of one form of the invention. Referring first to the figure, the main hoop 2 is pivoted, as at 1, to the side of the body of the vehicle- To this hoop is pivoted, as at a, the penultimate hoop 3. A little more than halfway up, the forward extension levers 4 are fulcrumed at Z) to the sides of the main hoop 2, while the forward hoop 5 is pivoted at its ends to intermediate points 0 on the extension levers 4'. A stop d at each end of the hoop 5 engages under the corresponding extension lever and limits the opening movement of the hoop 5.

At a point 0 about midway of the sides of the penultimate hoop 3 is fulcrumed the rear extension lever 6, the forward end of which is pivotally connected at f to the rear end of the forward extension lever 4:, while to the rear end of the extension leveps 6 is pivoted the rearmost hoop 7.

From an intermediate point on the side of the rearmost hoop 7 there extend links 10 linking said hoop with intermediate points near the upper part of the sides of the penultimate hoop 3.

In like manner, from an intermediate point on the sides of the forward hoop 5, there extend links 8 linking said forward hoop with points near the upper part of the sides of the main hoop 2.

Specification of Letters Patent.

Serial No. 123,647.

It will be seen that the parts 8, 7, 6 and 10 on the one hand, and parts 2, 5, eland 8 on the other hand, form trapezia having their extensions 4 and 6 pivotally connected at f, and that any folding movement of either of the end hoops positively causes a corresponding folding movement of the other and of the hoop 3 relative to the main hoop 2. After the stop (Z is reached, the hood is completely open, and at the same time brought into a locked position, so that no additional stretching can produce any further movement. All the stretching or tension stresses are therefore taken up by the iron construction itself, so that the yielding areas exposed to atmospheric influences, which in known constructions of hood have to take up a portion of the tension stress in order to give the hood rigidity, are com pletely relieved of any stress.

In long hoods the distance between the hoops 2 and 5 becomes so great that in order to obtain a pleasing hood line, the arrangement of an intermediate hoop 9 becomes advisable. It can be connected to the frame in any well known manner, but it is preferably pivotally connected as shown, so as to swing freely and to directly engage the material of the hood, in order to have, during erection, a convenient means for stretching the hood material for altering the inclination of the hoop. This stretching is merely to avoid creases in the hood material, and has nothing to do with the tension stresses which give rigidity to the frame, which stresses are taken up by the frame, as has been stated. It is noted that the hoop 9 may be omitted if desired.

For hoods of certain shapes, the angle formed by the rearmost hoop 7 and the extension levers 6 would be almost a straight angle, which is to be avoided.

I claim as my invention 1. In a folding hood, the combination of a main hoop; a penultimate hoop pivotally connected to the main hoop; a rear hoop; rear extension levers fulcrumed to the penultimate hoop and pivoted to the rear hoop; rear links above said levers and connecting the penultimate and rear hoops together; forward extension levers fulcrumed to the main levers and pivotally connected to the rear extension levers; a forward hoop pivotally connected to the forward extension levers and forward links above said forward extension levers and connecting the main hoop to the forward hoop; and a cover disposed over said hoop.

2. In a folding hood, the combination, with a vehicle or the like, of a main hoop pivoted to the vehicle; a penultimate hoop pivoted to the main hoop to swing to the rear thereof; a rear hoop; rear extension levers fulcrumed on the penultimate hoop and pivotally connected to the ends of the rear hoop; links above said levers and connecting intermediate parts of the penultimate and rear hoops together; forward extension levers fulcrumed on the main hoop and having their rear ends pivotally connected to the forward end of the rear extension levers; a forward hoop pivotally connected near its inner ends to the forward end of the forward extension levers and having its inner end turned and adapted to engage under the forward levers; and links above said forward levers and connecting the main hoop to an intermediate part of the forward hoop; and a flexible hood cover disposed over said hoops.

3. In a folding hood, the combination, with a vehicle or the like, of a main hoop pivoted to the vehicle; a penultimate hoop pivoted to the main hoop to swing to the rear thereof; a rear hoop; rear extension levers fulcrunied on the penultimate hoop and pivotally' connected to the ends of the rear hoop; links above said levers and con necting intermediate parts of the penultimate and rear hoops together; forward extension levers fulcrumed on the main hoop and having their rear ends pivotally connected near its inner ends to the forward end of the forward extension levers and having its inner end turned and adapted to engage under the forward devices; and links above said forward levers and connecting the main hoop to an intermediate part of the forward hoop; a flexible hood cover disposed over said hoops; and an intermediate hoop freely pivoted to said forward levers and adapted to be forced against the hood cover to stretch the same.

In witness whereof I have hereunto signed my name this 26th day of July, 1916, in the presence of two subscribing witnesses.
